Abstract
The invention relates to an electric pole falling-prevention device used for preventing electric poles from falling in the power industry, mainly comprising three arc support blocks and three pull rods, wherein , the three arc supporting blocks form a support ring through encircling, the three pull rods are respectively arranged at the end parts of every two support blocks and are articulated with the support ring by a bolt, so that the three pull rods are evenly distributed on the support rings, the upper parts of the pull rods are opened with pull holes, so that the constructors can fix the pull on the places which are out of reach of the constructors on the ground by the device without having to climbing up the electric poles, thus effectively ensuring safety of the constructors. Using the electric pole falling-prevention device in collaboration with the pull and a pull stake can effectively and reliably prevent the electrical poles from falling and breaking, thus preventing personal injury accidents caused by falling and breaking of the electrical poles.
Description
Technical field
The present invention relates to a kind ofly be used in power industry to prevent that electric pole from toppling over and the anti-reversing device for pole that uses.
Background technology
Electric pole is widely used in power industry as the bracing or strutting arrangement that is used for installing electric wiring, and electric pole has two types of metal electric pole and concurrents.For concurrent, if service time is long, it is not firm just to occur burying underground foundation easily, or the situation of crackle appears in electric pole, and if this moment is constructor's upper boom construction operation, takes place very easily then that electric pole is toppled over, disconnected bar and cause the accident of personal injury.
So, before constructor's upper boom construction operation, must carry out fixing reliably to electric pole for this electric pole that has potential safety hazard.Fixing at present mode is to play the stay cord stake on ground, is connected between electric pole and the stay cord stake with three stay cords, and with the stay cord tensioning.But because electric pole is too high, how one end of stay cord is fixed on the electric pole upper end is a stubborn problem, general method is to adopt anchor ear that stay cord is fixed on the electric pole upper end, and the structure of existing anchor ear is to have two blocks of curved metal derbies to be encircled into annulus, and fixed with bolt and nut at its two ends, but this needs the constructor to climb up electric pole just to finish equally, so the method that the anchor ear that adopts existing structure is fixed stay cord and electric pole is also infeasible.
Summary of the invention
The purpose of this invention is to provide a kind of anti-reversing device for pole, need not the constructor and climb up electric pole, just stay cord can be fixed on the position that electric pole upper ground surface constructor can't touch by this device.
Anti-reversing device for pole of the present invention is made up of arc back-up block and three pull bars of three radian unanimities, three back-up blocks surround the composition support ring, three pull bars lay respectively between the end of per two back-up blocks, and it is hinged with support ring between its two ends by bolt, three pull bars are evenly arranged on the support ring, the pull bar upper end offers the stay cord hole, the pull bar lower end is hinged with the hoop piece, the inner surface of hoop piece is an arc surface, between hoop piece and pull bar, extension spring is installed, extension spring one end is fixed on hoop piece upper end, and the other end is fixed on the pull bar.
During use, three bolts that will be used for hinged support ring and pull bar are earlier pulled down, three back-up blocks are separated, the stay cord stake is squeezed into underground (position, three places at stay cord stake place preferably is evenly arranged on the peripheral ground same circumference of electric pole) of electric pole periphery, then three back-up blocks are surrounded simultaneously on electric pole (this moment, three back-up blocks just consisted of support ring), and with pull bar with bolted splice on support ring (this moment three back-up blocks and three pull bars just form anti-reversing device for pole), anti-reversing device for pole is sleeved on the electric pole.Stay cord one end is fixed on the upper end of pull bar by the stay cord hole, the other end of stay cord is fixed in the stay cord stake, afterwards, with long pole or similar tool this anti-reversing device for pole is maybe needed the position fixed along moving to electric pole cracks top on the electric pole, again with three stay cord tensionings, pull bar is under the stay cord pulling, its lower end is drawn close to electric pole, and tightly conflict on electric pole the electric pole banding, thereby stay cord is fixed on the electric pole, electric pole is securely fixed on the ground by this anti-reversing device for pole, stay cord and stay cord stake.
Three back-up blocks are circular arc, and it is roughly rounded to make three back-up blocks surround the support ring of composition, can be convenient to like this anti-reversing device for pole is sleeved on the electric pole.
Three pull bars and support ring are hinged, make pull bar play the effect of lever, and undertaken hinged by bolt, can make the easy accessibility of three back-up blocks on the one hand, on the other hand, the support ring diameter that surrounds composition when three back-up blocks just can install pad additional during less than the diameter of electric pole lower end between pull bar and back-up block end, the support ring diameter is increased, thereby anti-reversing device for pole can be sleeved on the electric pole.
Three pull bars are evenly arranged on the support ring, the direction of three tightening forces that electric pole is subjected to is distributed rationally, thereby make the stressed distribution of electric pole reasonable, help the secure fixation of electric pole on ground.
The pull bar lower end is hinged with the hoop piece, and the inner surface of hoop piece is an arc surface, can increase the contact area of hoop piece and electric pole, and keep in touch with maximum area and electric pole assurance pull bar lower end.
Between hoop piece and the pull bar extension spring is installed, can guarantee to bind round piece does not produce in the pull bar lower end and saggingly (promptly binds round piece under its action of gravity, the inner surface of hoop piece is downwards towards ground), make anti-reversing device for pole when the banding electric pole, can guarantee that the inner surface that binds round piece contacts with electric pole.
Anti-reversing device for pole of the present invention is owing to have this kind structure, utilize lever principle, the pulling force of stay cord is conducted to the pull bar lower end, just can make the anti-reversing device for pole banding on electric pole, do not operate and do not need the constructor to climb up electric pole, guaranteed constructor's safety effectively; Be used by this anti-reversing device for pole and stay cord and stay cord stake, can effectively and reliably prevent the toppling over of electric pole, disconnected bar, avoided that electric pole is toppled over, disconnected bar and the generation that causes personal injury accidents.
